Study on the Ignition and Flame Structure of Diesel Combustion by Using Dual-component Fuels

Abstract

The authors have proposed the combustion control by using multi-component fuel spray. In this report, spray and ignition characteristics and flame structure were investigated for various two-component fuels. Various low boiling point components were mixed into high boiling point component to change vaporization and ignition characteristics of mixed fuel spray. In this step, the control of flame structure prevents the flame contacting with the chamber wall, and reduces heat loss. The optical measurements were carried out under the constant volume vessel. As an experimental result, physical and chemical characteristics of low boiling point fuel contained in mixed fuel affects with the ignition characteristics and flame structure.
